Traditional retailers are scrambling to catch up in the e-commerce space, particularly with Amazon, and as a result, management roles are being shaken up.

Top executives from both Walmart and Target are exiting the respective companies as the retailers look to adjust their business models and better meet consumer needs.

Both Walmart and Target are losing multiple executives:

Walmart:After acquiring Jet.com for $3 billion in August, former Jet CEO Marc Lore has taken over Walmart's e-commerce operations, which includes operating both sites' digital platforms. This month, Walmart is losing some of its core e-commerce team members, including Fernando Madeira, head of Walmart.com, Dianne Mills, SVP of global e-commerce human resources, and Brent Beabout, SVP of e-commerce supply chain, reports The Wall Street Journal.

Target:Target likewise has been experiencing a fundamental shakeup in its management. Last week it was announced that Target's grocery chief Anne Dament would be stepping down after just 18 months, reports Retail Dive. This follows the exit of Target's chief digital officer Jason Goldberger in September, and chief marketing officer Jeff Jones' departure in August. The firm reported a a 7% year-over-year (YoY) decline in total sales during Q2 2016.

Walmart's confidence in Lore to grow its overall digital business could signal a lack of success the company has with its own e-commerce division. While acquiring Jet.com could add to Walmart's overall online sales, simply onboarding the company does not address internal issues that remain, according to Columbia University professor Mark Cohen.

Leaning on Jet.com's assets could help propel Walmart's online business, but the company should remain committed to enhancing its current e-commerce operations outside of Jet.com as well in order to become a stronger player in the online market.

Target has faced numerous hurdles in the e-commerce market. It has struggled to find success with grocery — a product line that lends itself well to click and collect — and overall, digital still only accounts for 3.3% of total sales. Goldberger's exit after only four months in the role, along with other recent departures, highlights an instability within Target that could further push the company behind its competitors.
